Doritaenopsis plant named &#34;Sunrise Beautifil Girl&#34;

ABSTRACT

A new and distinct  Doritaenopsis  orchid plant named ‘Sunrise Beautiful Girl’ having attractive and unique purple-colored flowers with a very clear white edge and economical propagation via tissue culture. ‘Surnise Beautiful Girl’ has upright, sturdy flowering stems and excellent postproduction longevity.

BOTANICAL CLASSIFICATION

Doritaenopsis sp.

VARIETY DENOMINATION

‘Sunrise Beautiful Girl’.

The present invention relates to botanical classification/cultivar designation: Doritaenopsis Orchid cultivar Sunrise Beautiful Girl.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Doritaenopsis Orchid, hereinafter referred to by the cultivar name, Sunrise Beautiful Girl.

The new cultivar is a product of a planned breeding program conducted by the inventor in Taiwan. The objective of the breeding program is to create new uniform pot-type Doritaenopsis Orchid cultivars having attractive flower coloration.

The new cultivar breeder was Hou-Chih Lin. The new cultivar was discovered by the inventor from within the progeny of a cross-pollination of two identified proprietary selections of Doritaenopsis Orchid, not patented, on Mar. 3, 1994, in a controlled environment in Taiwan. Later, it was verified and registered in Royal Horticulture Society (R.H.S.) and had its variety name “Dtps. Sunrise Beautiful Girl” on January, 2003.

Asexual propagation by tissue culture in a laboratory in Taiwan has been used to increase the number of plants for evaluation and has demonstrated that the unique combination of characteristics as herein disclosed for the new Doritaenopsis Orchid are firmly fixed and are retained through successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of new cultivar which, in combination, distinguish this Doritaenopsis Orchid as a new and distinct cultivar:

1. Petal main color: purple; Petal color pattern: white edge.

2. Purple-colored flowers with a very clear white edge and greyed purple-colored labellum.

3. Freely flowering habit.

4. Upright, sturdy flowering stems.

5. Excellent postproduction longevity.

Plants of the new cultivar differ primarily from plants of the parent cultivars in flower color.

Plants of the new Doritaenopsis Orchid can be compared to plants of the cultivar Dtps. Ruey Lih Beauty, differing from plants of the cultivar Dtps. Ruey Lih Beauty the following characteristics:

1. Plants of the new Doritaenopsis Orchid are larger than plants of the cultivar Dtps. Ruey Lih Beauty.

2. Plants of the new Doritaenopsis Orchid are more freely flowering than plants of the cultivar Dtps. Ruey Lih Beauty.

3. Plants of the new Doritaenopsis Orchid have more flowers per inflorescence than plants of the cultivar Dtps. Ruey Lih Beauty.

4. Plants of the new Doritaenopsis Orchid have larger flowers than plants of the cultivar Dtps. Ruey Lih Beauty.

5. Plants of the new Doritaenopsis Orchid and the cultivar Dtps. Ruey Lih Beauty differ in flower color. The color of petal and sepal are purple and bright with a very clear white edge.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Plants of the new cultivar have not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature and light intensity, without however, any change in genotype. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
